AD9833WBRMZ-REEL

Overview

The AD9833WBRMZ-REEL is a low-power, programmable waveform generator from Analog Devices Inc., housed in a 10-lead MSOP package. It operates on a 2.3 V to 5.5 V supply and consumes 12.65 mW at 3 V. The device features a 10-bit DAC with an update rate of 25 MSPS and produces sinusoidal, triangular, and square wave outputs ranging from 0 MHz to 12.5 MHz. Frequency and phase are digitally programmable via a 3-wire SPI interface compatible with DSP standards. It includes a 28-bit frequency register for high resolution and supports power-down modes to minimize current consumption.

Feature Summary

• Digitally programmable frequency and phase control
• Produces sine, triangular, and square wave outputs
• Integrated 3-wire serial interface compatible with standard protocols
• Power-down function allows selective section shutdown

Applications

• Frequency stimulus and waveform generation
• Liquid and gas flow measurement
• Proximity, motion, and defect detection sensing
• Time domain reflectometry (TDR) applications

Procurement Notes

Verify the specific suffix REEL indicates tape and reel packaging when sourcing. Confirm the automotive qualification status if required for the final design, as specifications may vary between industrial and qualified grades. Ensure the ordering part number matches the exact temperature range and performance grade needed for the application environment.

Selection Notes

Select this component for applications requiring software-tunable waveform generation without external components. Consider the 28-bit frequency resolution and 10-bit DAC accuracy for signal purity requirements. Verify that the host microcontroller can support the 3-wire serial interface timing constraints and voltage levels within the 2.3 V to 5.5 V operating range.

Part Context

This part belongs to the AD9833 series of direct digital synthesizers. The WBRMZ variant specifically denotes the wide temperature industrial grade (-40°C to +105°C) in a 10-lead MSOP package. It is designed for low-power embedded systems where precise frequency synthesis is needed without complex external circuitry.

Replacement Considerations

The AD9833BRMZ-REEL is a verified substitute offering identical functionality but potentially different automotive qualification status. Both parts share the same pinout, package, and electrical specifications.
